v SPECIFICATION forming` part of Letters Patent No. 536,876, dated April 2, 1895.

Application filed January 22, 1895. Serial No. 535.832. (No model.)

To all whom it may concer-n: Y

Be it known that I, EvAN W. JoNEs, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Stump-Fullers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in stump pullers and it consists of the combination with a suitable frame, of a shaft mounted in the same, a winding drum on said shaft, a hand lever for operating said shaft, a sweep attaching plate mounted in proximity to said hand lever, and means for connecting said plate to said lever at will, whereby they may operate separately or together.

It also consists of the combination of a separable frame having strengthening cones provided with loops to which the anchor attaching olevis is secured,` a winding drum journaled in said frame and means for operating said drum.

\ It also consists of certain other novel combinations, constructions and arrangements of parts, all of which will be hereinafter more particularly set forth and claimed.

In the accompanying drawings, Figure 1. represents a perspective View of the devices embodying my invention. Fig. 2. is a top plan view of the same, the hand lever and sweep supporting plate being removed and the shaft shown in section. Fig. 3. represents a central vertical section through my said devices on the line X-X of Fig. 2. Fig. 4. represents a detail top plan view of the hand operating lever. Fig. 5. represents a detail top plan view of the sweep plate and the end of a sweep lever, showing the manner of attaching the said sweep lever thereto, and Fig. 6. represents a detail vertical section of one of the hollow studs of the sweepplate showing the hand lever engaging pin.

Ain the drawings, represents the sled 0r other carriage upon which my machine is mounted and by which it is conveyed from one point to another of operation. A frame B is secured to this sled by bolts p which pass through lugs b of said frame and said sled.

The rear end of the lower half C of this frame is curved upward to meet the rear downwardly curved end of the upper half C. Both of the frames C and O are provided with strengtheningcores c, preferably of steel. These cores have their front ends secured in plates b2, preferably of steel, by nuts b3 which screw on the screw threaded ends of said cores. The cores pass rearwardly through the respective halves of the frame in grooves c', b4 in said `frame until they reach the upwardly and downwardly extending portions of said frame when they enter passages c2 b5 in said frame and form loops o3 b6 at the rear end of the frame; the core of each half frame being a continuous unbroken rod.

The rear end of the half frames O and O are secured together by a bolt d. An anchor attaching clevis D is secured to the looped portions c3 be of the cores by a bolt d and thus any strain brought to bear upon the clevis will be'received by the continuous cores c and plates b2 and thus the frame will be relieved `of much of said strain.

A winding. drum E is mounted between the forward separated ends of the half frames, C and C', upon a squared shaft E. The said half frames are retained in a separated positionwithout bearing upon the top or bottom of said drum, by hollowcolumns or standards e which are interposed between said frames and kept in position by bolts e which pass through said standards and frames and are secured in position by nuts.

The lower flange of the drum E is provided about its periphery with a rack e2 which is adapted to be engaged by a pawl F which is pivoted between said half frames, C and O and has its upper pivot point extended to form a spring attaching stud f to which one end of springf is rigidly attached, the other end of said spring being adapted to be passed behind a projection c5 on frame O or be released therefrom at will and thereby cause said pawl to engage or disengage with the rack e2 according as to whether it is desired to turn the drum backward or not. w

The lower end of the shaft E is rounded to form a journal e4 which ts within a recessin the half frame O. at a short distance below its upper end, at e5 to form its upper journal. The journal boX IOO Said shaft is also rounded 'Y h is composed of two half boxes which are set in an approximately rectangular recess c5 in the top of the frame C and are provided with upper flanges h' which retain them in position. The hand lever G as shown in Fig. Ll,

is provided with a central stud g having aA square passage g through it, and end notches g2. This hand lever lis slipped over the upper end of the squared shaftE and rests upon the top of the frame C. Any movement of this lever G will of course revolve the shaft E and the winding drum carried thereby. A sweep carrying plate I is provided near its center with a passage t' surrounded by an upwardly extending collar t; said sweep plate being adapted to be slipped on top of the hand lever G with the part g of the same extending through the passage t' thus leaving the sweep plate free to move without affecting the hand lever.

The sweep plate is approximately rectangular in form and is provided at diametrically opposite corners with upwardly projecting studs t2. These studs are each provided with vertical passages t3 having vertical slots 714 cut in the walls thereof, the latter extending only half way down the said passages. Locking pins J, each provided with a projecting stud j are adapted to work vertically in said passages i3 with the studs j in the slots t4. See Fig. 6. V'Vhen it is desired to canse the sweep plate to engage with and move the hand lever G the pins .I are turned so that the studs jof the said pins J correspond in position with the slots t4 when said pins will descend and the lower projecting ends will engage the notches g2 of the hand lever, when the sweep plate is rotated, and thus cause the shaft E to be revolved.

A sweep lever K is secured to the top of the plate I by yokes k which pass over said sweep and have their ends secured to the said plate by bolts 7c,'the formation of the sides of the studs 2, against which said sweep bears, being such as to conform to the shape of said lever and thus give it a firm seat against said studs. It will be observed that all the parts of my machine are interchangeable and by removing the shaft E, any part can be removed or repaired without difficulty.

The operation of the machine is as follows: The machine is first brought near a stump, and a steel cable or chain passed around the stump and through the clevis D, thus anchoring the machine firmly. One end of a steel cable of suitable length is passed through the upper Iiange of the drum and firmly secured thereto, and as much of the cable as may be dcsired is wound around the drum. To the other end of this cable is secured a suitable hook for grappling roots, brush or the like, or for forming a hitch around the stu mp to be pulled. Whereit is desired to use a snatch block for the purpose of increasingthe power, the shackle on said block is hitched by means of a short rope or chain to the stump that is to be pulled and the drum rope is then passed around the sheave of the snatch block and to a second stump or other anchorage. The horse or horses are now hitched to the end of the sweep lever K, and said horses are caused to move in a circle, and when the pins are lowered, `a rotary motion will be imparted to the drum and the steel cable will be wound on the same thus exerting a pulling strain on the rope in proportion to the strength of the horses, the length of the sweep, and the diameter of the drum. When it is desired to take up any slack in the pulling rope after pulling a stump I let the horses stand, lift the pins J, and give them a partial revolution so that the studsj on their sides will rest on top of the studs i2. The lower ends of these pins will then clear the lever G, and the operator then by means of this lever has complete control of the drum, winding or unwinding loose rope quickly at his pleasure. After the hitch has been made to another stump and the slack rope has been taken up, the pins are dropped into their former position, the horses are started up and the work goes on without the serious loss of time that would be unavoidable in using a machine without this improvement.

Vhat I claim as my invention, and desire to secure by Letters Patent, is-
